The Steelhead X-14 line offers the best technology. The key is the variable face thickness, a manufacturing process that effectively moves weight around the head to optimize the performance characteristics. The short irons have a higher center of gravity, which keeps the ball from ballooning too high, and that leads to better control. The rounded soles make it easier to take shallow divots for crisper contact. The sleek finish belies the maximum perimeter weighting.
